OPERATING TIPS
When the engine coolant temperature and out-
side air temperature are low, the air flow from
the foot outlets may not operate. However, this
is not a malfunction. After the coolant tempera-
ture warms up, the air flow from the foot outlets
will operate normally.
The sensors
AandBlocated on the instru-
ment panel help maintain a constant tempera-
ture. Do not put anything on or around the
sensors.
IN-CABIN MICROFILTER
Models without Advanced Climate Control Sys-
tem:
The climate control system is equipped with an
in-cabin microfilter which collects dirt, pollen,
dust, etc. To make sure the air conditioner
heats, defogs, and ventilates efficiently, replace
the filter in accordance with the maintenance
schedule in the INFINITI Service and Mainte-
nance Guide. To replace the filter, contact an
INFINITI retailer.
The filter should be replaced if air flow is ex-
tremely decreased or when windows fog up eas-
ily when operating heater or air conditioning
system. Models with Advanced Climate Control System:
The climate control system is equipped with a
natural grape seed polyphenol filter which col-
lects and neutralizes dirt, pollen, dust, etc. To
make sure that the air conditioner heats, defogs
and ventilates efficiently, replace the filter in
accordance with the maintenance schedule in
the INFINITI Service and Maintenance Guide. To
replace the filter, contact an INFINITI retailer.
The filter should be replaced if the air flow de-
creases significantly or if windows fog up easily
when operating the heater or air conditioner.SAA3088

Your new INFINITI has been designed to have
minimum maintenance requirements with long
service intervals to save you both time and
money. However, some day-to-day and regular
maintenance is essential to maintain your IN-
FINITI’s fine mechanical condition, as well as its
emission and engine performance.
It is the owner’s responsibility to make sure that
the scheduled maintenance, as well as general
maintenance, is performed.
As the vehicle owner, you are the only one who
can ensure that your vehicle receives the proper
maintenance care. You are a vital link in the
maintenance chain.
SCHEDULED MAINTENANCE
For your convenience, both required and op-
tional scheduled maintenance items are de-
scribed and listed in your “INFINITI Service and
Maintenance Guide”. You must refer to that
guide to ensure that necessary maintenance is
performed on your INFINITI at regular intervals.
GENERAL MAINTENANCE
General maintenance includes those items
which should be checked during normal day-to-
day operation. They are essential for proper
vehicle operation. It is your responsibility to
perform these procedures regularly as pre-
scribed.
Performing general maintenance checks re-
quires minimal mechanical skill and only a few
general automotive tools.
These checks or inspections can be done by
yourself, a qualified technician or, if you prefer,
an INFINITI retailer.
WHERE TO GO FOR SERVICE
If maintenance service is required or your ve-
hicle appears to malfunction, have the systems
checked and serviced by an INFINITI retailer.
INFINITI technicians are well-trained specialists
and are kept up to date with the latest service
information through technical bulletins, service
tips, and in-retailership information systems.
They are completely qualified to work on
INFINITI vehiclesbeforework begins.
You can be confident that an INFINITI retailer’s
service department performs the best job to
meet the maintenance requirements on your
vehicle — in a reliable and economical way. During the normal day-to-day operation of the
vehicle, general maintenance should be per-
formed regularly as prescribed in this section. If
you detect any unusual sounds, vibrations or
smell, be sure to check for the cause or have an
INFINITI retailer do it promptly. In addition, you
should notify an INFINITI retailer if you think
that repairs are required.
When performing any checks or maintenance
work, see “MAINTENANCE PRECAUTIONS” later
in this section.
EXPLANATION OF MAINTENANCE
ITEMS
Additional information on the following items
with “*” is found later in this section.
Outside the vehicle
The maintenance items listed here should be
performed from time to time, unless otherwise
specified.
Doors and engine hood:
Check that all doors
and the engine hood, operate properly. Also
ensure that all latches lock securely. Lubricate
hinges, latches, latch pins, rollers and links if
necessary. Make sure that the secondary latch
keeps the hood from opening when the primary
latch is released.

Maintenance and do-it-yourself8-17

REPLACING SPARK PLUGS
If replacement is required, see an INFINITI re-
tailer for servicing.
Iridium-tipped spark plugs
It is not necessary to replace the iridium-tipped
spark plugs as frequently as the conventional
type spark plugs since they will last much
longer. Follow the maintenance schedule in
“INFINITI Service and Maintenance Guide”, but
do not reuse them by cleaning or regapping.
Always replace spark plugs with recommended
or equivalent ones.To remove the filter, release the lock pins
1
and pull the unit upward2.
The filter element should not be cleaned and
reused. Replace it according to the mainte-
nance intervals. See “INFINITI Service and Main-
tenance Guide” for maintenance intervals.
When replacing the filter, wipe the inside of the
air cleaner housing and the cover with a damp
cloth.
WARNING
● Operating the engine with the air cleaner
removed can cause you or others to be
burned. The air cleaner not only cleans the
air, it stops flame if the engine backfires. If it
isn’t there, and the engine backfires, you
could be burned. Do not drive with the air
cleaner removed, and be careful when work-
ing on the engine with the air cleaner
removed.
● Never pour fuel into the throttle body or at-
tempt to start the engine with the air cleaner
removed. Doing so could result in serious
injury.

Change intervals
The oil and oil filter change intervals for your
engine are based on the use of the specified
quality oils and filters. Oil and filter other than
the specified quality, or oil and filter change
intervals longer than recommended could re-
duce engine life. Damage to engines caused by
improper maintenance or use of incorrect oil
and filter quality and/or viscosity is not covered
by the new INFINITI vehicle limited warranties.
Your engine was filled with a high quality
engine oil when it was built. You do not have to
change the oil before the first recommended
change interval. Oil and filter change intervals
depend upon how you use your vehicle. Opera-
tion under the following conditions may require
more frequent oil and filter changes.
●repeated short distance driving at cold out-
side temperatures,
● driving in dusty conditions,
● extensive idling,
● towing a trailer,
● stop and go “rush hour” traffic,
Refer to the “INFINITI Service and Maintenance
Guide” for the maintenance schedule.
AIR CONDITIONING SYSTEM
REFRIGERANT AND LUBRICANT
RECOMMENDATIONS
The air conditioning system in your INFINITI ve-
hicle must be charged with the refrigerant HFC-
134a (R-134a) and the lubricant, NISSAN A/C sys-
tem oil Type S or the exact equivalents.
CAUTION
The use of any other refrigerant or lubricant will
cause severe damage to the air conditioning
system and will require the replacement of all
air conditioner system components.
The refrigerant HFC-134a (R-134a) in your
INFINITI vehicle will not harm the earth’s ozone
layer. Although this refrigerant does not affect
the earth’s atmosphere, certain governmental
regulations require the recovery and recycling
of any refrigerant during automotive air condi-
tioning system service. Your INFINITI retailer
has the trained technicians and equipment
needed to recover and recycle your air condi-
tioning system refrigerant.
Contact an INFINITI retailer when servicing your
air conditioning system.
Technical and consumer information9-7

Always block the wheels on both vehicle and
trailer when parking. Parking on a slope is not
recommended; however, if you must do so:
CAUTION
If you move the shift selector lever to the P
(Park) position before blocking the wheels and
applying the parking brake, transmission dam-
age could occur.
1. Apply and hold the brake pedal.
2. Have someone place blocks on the down-hill side of the vehicle and trailer wheels.
3. After the wheel blocks are in place, slowly release the brake pedal until the blocks
absorb the vehicle load.
4. Apply the parking brake.
5. Shift the transmission into P (Park).
6. Four-Wheel Drive (4WD) models:
Make sure that the 4WD shift switch is
engaged in the AUTO, 4HI or 4LO position
and the Automatic Transmission (AT) park
warning light is turned off.
7. Turn off the engine.
To drive away:
1. Apply and hold the brake pedal.
2. Start the engine.
3. Shift the transmission into gear.
4. Release the parking brake.
5. Drive slowly until the vehicle and trailer
are clear from the blocks.
6. Apply and hold the brake pedal.
7. Have someone retrieve and store the blocks.
● While going downhill, the weight of the
trailer pushing on the tow vehicle may de-
crease overall stability. Therefore, to main-
tain adequate control, reduce your speed
and shift to a lower gear. Avoid long or
repeated use of the brakes when descending
a hill, as this reduces their effectiveness and
could cause overheating. Shifting to a lower
gear instead provides “engine braking” and
reduces the need to brake as frequently.
● If the engine coolant temperature rises to a
high temperature, see “IF YOUR VEHICLE
OVERHEATS” in the “6. In case of emer-
gency” section.
● Trailer towing requires more fuel than nor-
mal circumstances. ●
Avoid towing a trailer for your vehicle’s first
500 miles (800 km).
● Have your vehicle serviced more often than
at intervals specified in the recommended
maintenance schedule in the INFINITI Service
and Maintenance Guide.
● When making a turn, your trailer wheels will
be closer to the inside of the turn than your
vehicle wheels. To compensate for this,
make a larger than normal turning radius
during the turn.
● Crosswinds and rough roads will adversely
affect vehicle/trailer handling, possibly
causing vehicle sway. When being passed by
larger vehicles, be prepared for possible
changes in crosswinds that could affect ve-
hicle handling.
Do the following if the trailer begins to sway:
1. Take your foot off the accelerator pedal to allow the vehicle to coast and steer as
straight ahead as the road conditions
allow. This combination will help stabilize
the vehicle.
– Do not correct trailer sway by steering orapplying the brakes.
2. When the trailer sway stops, gently apply the brakes and pull to the side of the road
in a safe area.
